The wick is made of a high grade of cotton or linen. The material is woven (or braided) so that it will burn in one direction and will curl so that its end remains in the candle flame's oxidizing zone for even and intense burning. Often, wire-core wicks are used.
Differentiate among the non-urinary waste management systems. The excretory system is a passive biological system that removes excess and unnecessary materials from the body, so as to help maintain homeostasis and prevent damage. The main organs involved in waste management are the skin, lungs, liver, and kidneys.
The excretory system is a system of organs that removes waste products from the body. When cells in the body break down proteins (large molecules that are essential to the structure and functioning of all living cells), they produce wastes such as urea (a chemical compound of carbon, hydrogen, nitrogen, and oxygen).reter: Tube that carries urine from a kidney to the urinary bladder. Urethra: Duct leading from the urinary bladder to outside the body through which urine is eliminated. The waste-containing fluid that remains in the nephrons is called urine.
